If you have ideas about things you'd like to see us cover in a future, week-long mini-series, drop a suggestion in the comments below.

"All You Need Is Love"

This is a unique song not only in The Beatles' catalog, but as pop songs go in general. The first performance of the song was seen live by 400 million people across 26 countries, via satellite on 25 June 1967. The BBC had commissioned The Beatles to write a song for the United Kingdom's contribution to the live, international, satellite television production that also included opera singer Maria Callas and painter Pablo Picasso. That's some pretty heavy company!
